To all whom itm'ag concern:

Be it known t-hatI, FRA GJTERRY, a

citizen ofthe United States, residing hnas, in'the county of Monterey and State of Califorriia;haveinvented'certain new and useful Improvements in "Beet Shreddersyof which the following is a specification;

This invention relates to vegetable cutters, particularly beet-shredders, and especially to knives forbeet-Shredders o'f'the type in which the knives. are arranged in the revoluble bottom of a stationary. cylindrical hopper, the beets being .broughtinto contact with the knives tofperform the shredding by he revolution of thethopper bottomin conjunction with the superimposed Weight of the IIIHSS'Of hQGtSTIlPOIlithGjkIliYGS. y

The knives noW in use in this type of shredder-have a vertical or square zcuttii g edge against which thejbeets :are'fforce'dias the hrpper bottom h revolves, but this type of knife is often ruined by hard foreign matter, such as stones or pieces of gir'on,

vh'ch in coming into-contact Withgthe cuttin g edge, Which is necessarily veny thin a d sharp. breaks thlS' edge and hence makes the knife useless. its thesejknives are rather expensive, such' breakage is an item o'fconsiderable importance. It is one; of "the objects'of this invention'to soformthe cutting edge of the knife that it isalmost'impossibh ,for it toibe broken in the manner; abovefdescribed.

Another object of the invention; is to so support the cuttln g edge 1 of the knife f means of a throat-piece thatforeign matter will not be wedged in' the throat ofjthe Ajfurtlier. zobject of the invention'vis; to, so

form the throat-piece that .the beets .wvill always present a surface "forthe f kfnife to cut. The invention "consists in af kni'feifor' beet shredders and" the likefhavinga'cutting edge inclined rearivardly from bottom to top and adapted to cooperate "With a throat-piece which, is slotted to support .and,,shieldt,the

with I having knives of this type, the knife makes cutting edge of the" knife and provide; means for adjusting it With relation to "the knife to vary the cut made, and having face "for theiknifet edge to cut all as will proceed now to explain and ffinallyi claim.

In the accompanying 'drawings illustrating'the invention, inthe several figures of Which like parts are similarlyidesignated, Figure '1 is a plan View of a block on which the shreddingjknife and its coactingvparts are mounted. Fig. 2 is a vertical section taken in the plane of line A'B, 'IEi-g. 1. Figi3is afragmentary perspective view of the knife. Figs. 4- ancl5are side elevations of'two modified "forms of knife.

The cutter-block 1 has a central discharge opening 2, at one side of which the knife 3 is suitably secured by means of screws 4% or 'otherffastenings in a recess 5. In .a recess 16 atthe opposite side of the opening 2 is mounted a throat-piece 7, 'lieldrigiclly in positionbytmeansof screWs8 which clamp "it down upon the upper ends of adjusting screws 9. Although Ihavei herein illustrated this particular means for adjusting .the

throat-piece ithrelation to theknife, it is ,obvious'that othersuitable means might be equally well used.

The knife3'has an attaching plate 110,

from which extends the cutter proper,

"formed in a. series offlutes-ll tapered to a sharp edge and having downwardly projectingblades 12,211.50 sharpened on their e'dgesi13.

"Inthe'knivesmw in use the cutting edge gis vertical, but I find that in the use of j'kriives so madehardi foreign matter, such as stones and pieces of iron, Will strikeabruptly against the edge With such force astotbreak it: and. therebyruinflthe knife. [*In the knife off this inventionthe cutting edgelitis'heveled, or? inclinedrearvva 'lClLY fromibottomgto i top, so that when any jforeign substances strike'itthey will tend'to ride over rather than jam against it.

'{Thej throat -piece 7 is provided in one edge vvi'th aseries of slots 14 so spaced asito receive thebladeslQ and prevent lateral movement" thereof siflficient;to, break.i them. Fur t ermore, he ensn f orm "by thes slots extend between theblades 12 sufliciently far and in such manner as to preventthe op n n re a e ns esse t TWhen" beets are "shredded vvitha machine beet will merely slide over the knife with out being cut. To obviate this the upper face of the throat-piece 7 is provided with grooves 16 in line with the blades 12, and any beets presented to the knife as above described, will be sufliciently lowered with respect to the knife to. admit of a out being made.

Although the preferred form of knife has a straight cutting edge 13, as shown in Figs. 1, 2 and 3, the edge may be made either convex or concave, as shown in Figs. 4 and 5 respectively.

Although the operation of the device seems obvious, it may be well to say that as the hopper bottom revolves, the beets are pressed down on the bottom by their own weight, and the knives are drawn under 7 them to shred them, the shreds passing between the blades 12 and out of the opening 2 to a receiver.

It is to be understood that I do not limit my invention to the particular details of construction herein shown and described, as it is obvious that various changes may be made without departing from the spirit of the invention or the scope of the appended claims. Nor do I wish to limit its application to beet shredders alone, as it may be equally well used otherwise.

What I claim is I 1. A cutter for beet shredders and the like comprising a cutter block having a discharge slot, a fluted knife secured to the block on one side of the slot and having its cutting edge extending over the slot and blades depending from the lower parts of the flutes and projecting forwardly therefrom, said blades having cutting edges inclined downwardly and forwardly from. the cutting edge of said knife, and a throat piece projecting from the opposite side of the slot and having grooves in its projecting end into which the forward ends of said, blades extend, and intervening'tongues.

2. A cutter for beet shredders and the like comprising acutter block having a dis charge slot, a fluted knife secured to the block on one side of the slot and having its cutting edge extending over the slot and blades depending from the lower parts of the flutes and projecting forwardly therefrom, said blades having cutting edges inclined downwardly and forwardly from. the cutting edge of said knife, and means for supporting the forward ends of said blade against lateral movement.

from, said blades having cutting edges in-' clined downwardly and forwardly from the cutting edge of said knife, and a throat piece projecting from the opposite side of the slot and having grooves in its projecting end into which the forward ends of said blades extend, the upper surface of said throat piece having alternate grooves and ridges in line with the blades and'flutes, respectively.

4. A cutter for beet shredders and the like comprising a cutter block having a discharge slot, a fluted knife secured to the block on one side of the slot and having its cutting edge extending over the slot and blades depending from the lower parts of the flutes and projecting forwardly there from, said blades having cutting edges inclined downwardly and forwardly from the cutting edge of said knife, and a throat piece projecting from the opposite side of the slot and having grooves in its projecting end into which the forward ends of said.

blades extend, and interveningtongues ex tending substantially to the fluted cutting edge of said knife.

-5. A cutter for beet shredders and the like comprising a cutter block having adischarge slot, a fluted knife secured to the block on one side of the slot and having its cutting edge extending over the slot and blades depending from'the lower parts of the flutes and projecting forwardly there from, the cutting edges of said flutes and blades being forwardly and downwardly inclined, and althroat piece projecting from the opposite side of the slot and having grooves in its projecting end into which the forward ends of said blades extend. and intervening tongues.

6. In a cutter for beet shredders and the like, a knife having a fluted cutting edge FRANK G. TERRY.
